Find the coordinates of the point that is two-fifths of the distance from (-2, 1) to (8, 11)

U have to rearrange to find x.
So first u look at the equation and u see u have to - 29 as u have to get x on its own.
This leaves u with:
6<3x
Now u have to divide by 3 to finally get x on its own, so this would leave u with the
2<x

And the number line which represents this is B.
